SAFETY INFORMATION
Warning!This product is not for household use. It presents risks of
lethal or severe injury due to fire and heat, electric shock, and
falls.
Read this manual before powering or installing the fixture, follow the
safety precautions listed below and observe all warnings in this manual
and printed on the fixture. If you have questions about how to operate the
fixture safely, please contact a Martin distributor for assistance. Refer any
service operation not described in this manual to a qualified technician.
Do not modify the fixture or install other than genuine Martin accessories
and upgrade kits.
Avoiding electric shocks
• Disconnect the fixture from AC power before removing or installing the
lamp, fuses, or any part, and when not in use.
• Always ground (earth) the fixture electrically.
• Use only a source of AC power that complies with local building and
electrical codes and has both overload and ground-fault protection.
• Do not expose the fixture to rain or moisture.
• Refer all service to a qualified technician.
• Never operate the fixture with missing or damaged lenses and/or covers.
Introduction5
Page 6
Protecting yourself and others from burns and fire
• Never attempt to bypass the thermostatic switch or fuses. Always replace
defective fuses with ones of the specified type and rating.
• Ensure that the air flow through fans and vents is free and unobstructed.
• Keep all combustible materials (for example fabric, wood, paper) at least
0.1 meters (4 inches) away from the fixture. Keep flammable materials
well away from the fixture.
• Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture.
• Provide a minimum clearance of 0.1 meters (4 inches) around fans and air
vents.
• Replace the lamp if it becomes defective or worn out, or when average
service life is reached. When replacing the lamp, allow the fixture to cool
for at least 15 minutes before opening the fixture or removing the lamp.
• Never place filters or other materials over the lens or mirror.
• The exterior of the fixture can become hot. Allow the fixture to cool for at
least 5 minutes before handling.
• Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C
(104° F).
• Do not stare directly into the light.
• Never operate the fixture without all lenses and covers installed: an
unshielded lamp emits UV radiation that can cause burns and eye
damage.
Preventing injuries due to falls
• When suspending the fixture above ground level, verify that the structure
can hold at least 10 times the weight of all installed devices.
• Verify that all external covers and rigging hardware are securely fastened
• Use an approved means of secondary attachment such as a safety cable.
• Block access below the work area when installing or removing the fixture.

Verify that the clearance around the air vents is at least 0.1 meters (4 in.).
OPERATION FROM THE FLOOR
To operate the Ego X4 from the floor:
1 Set the fixture on the floor so that the
mounting bracket is under the fixture. Adjust
the mounting bracket and tighten both swivel
locks. Note that the fixture may not be placed
so that the clearance around the air vent is
impaired.
2 Verify that the fixture is stable, that it is at
least 0.3 meters (12 in.) from the surface to
be illuminated and at least 0.1 meters (4 in.)
from any combustible materials. Verify that
the clearance around the air vents is at least
0.1 meters (4 in.).
Do not operate the fixture while it lies flat
without the mounting bracket extended as
this reduces the air flow to the fan; the fixture
may overheat and then the thermal
protection switch will temporarily cut the power.

ATA CONNECTION
This section describes how to connect fixtures to each other, or to a
controller.
RECOMMENDED CABLE
A reliable data connection begins with the right cable. Standard
microphone cable cannot transmit DMX data reliably over long runs. For
best results, use cable specifically designed for RS-485 applications. Your
Martin dealer can supply high quality cable in various lengths.
CONNECTIONS
The Ego X4’s XLR data sockets are wired with pin 1 to ground, pin 2 to
signal - (cold), and pin 3 to signal + (hot). This is compatible with the
standard for DMX devices.
One or more adaptor cables may be required to connect the Ego X4 to the
controller and/or other lights because many devices have 5-pin
connectors and others may have reversed signal polarity, that is, pin 2 hot
and pin 3 cold.

Connecting the data link
1 Connect a data cable to the controller’s output. If controller has a 5-pin
output, use a 5-pin male to 3-pin female adaptor (P/N 11820005).
2 Lead the data cable from the controller to the first fixture. Plug the cable
into the fixture’s data input.
3 Connect the output of the fixture closest to the controller to the input of the
next fixture. If connecting two fixtures with opposing polarity on pins 2 and
3, insert a phase-reversing cable between the two fixtures.
4 Continue connecting fixtures output to input. Up to 32 devices may be
connected on a serial link.
5 Terminate the link by inserting a male termination plug (P/N 91613017)
into the data output of the last fixture. A termination plug is simply an XLR
connector with a 120 Ohm, 0.25 W resistor soldered across pins 2 and 3.

TAND-ALONE OPERATION
The Ego X4 may be operated without a controller in stand-alone mode. It
can be operated as a single unit or together with other Ego X4s in a
“master/slave” configuration.
Several options are available to modify stand-alone operation. These
options are selected using the DIP-switch and are described in this
chapter.
Important!The Ego X4 transmits a signal when DIP-switch p ins 1 or 2 and
10 are set to ON. To avoid damage to the el ectronic s, connec t
no more than 1 tran smitting devi ce (master or controller) t o
the data lin k.
STAND-ALONE SETTINGS
DIP-switch pins 1, 2, 4, 5, 6 and 8 enable stand-alone options only when
pin 10 is ON. When pin 10 is off, the DIP-switch selects a DMX address.
Pin 11 must be OFF for stand-alone operation.

Demo program
If DIP-switch pins 5 and 10 are both set to ON, the fixture runs a factoryset program that demonstrates all its effects.
MASTER / SLAVE OPERATION
Multiple Ego X4s can be connected together, without a controller, for
synchronized “master/slave” operation in which the slaves mimic, or
respond to, the behavior of the master.
Connecting units for master / slave operation
1 Connect the output of one Ego X4 to the input of the next Ego X4.
2 Connect additional Ego X4s output to input. Up to 32 may be connected.
3 Terminate the link on both ends by inserting a female termination plug into
the data input of the first fixture and a male termination plug into the data output of the last fixture. (The female terminator may not be required if the
first fixture is the master.) A termination plug is simply an XLR connector
with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3.
Setting the master
Import ant!Set only 1 fixture as master (DIP-switch pins 1 or 2 and 10 ON).
1 Set DIP-switch pins 10 to ON.
2 Set DIP-switch pins 3, 5, 6, 7, 8, 9, and 11 to OFF.
3 Select trigger options with DIP-switch pins 1 or 2 and effect speed with pin
4 (see “Stand-alone settings’ on page 15).
Setting a slave
1 Set pins 1, 2, 3, 4, 5, 7, 9 and 11 to OFF.
2 Select options with DIP-switch pins 6 and 8 (see “Stand-alone settings’ on
page 15). If you use these options then you must also set DIP-switch 10 to
ON. If none of these options are set then the slave fixture will mimic the
master exactly. Use these options if you want a slave fixture to behave
differently, for example, to make a show more interesting.
16Ego X4 user manual
Page 17
DMX
OPERATION
The Ego X4 can be connected to and operated from a DMX controller.
DMX CONTROL ADDRESS
The control address, also known as the start channel, is the first channel
used to receive instructions from the controller. Each fixture needs its own
control address set, and uses this address and subsequent control
channels to receive instructions from a controller. The Ego X4 uses six
control channels.
The Ego X4 reads the data on the start channel and the next five
channels. If the DMX control address is set to 100, the fixture uses
channels 100, 101, 102, 103, 104 and 105. Channel 106 is available for
use as control address for the next fixture.
For independent control, each fixture must be assigned its own address
and non-overlapping control channels. If two or more fixtures are set up
with the same address, they will receive the same instructions and should
behave identically. Setting up identical fixtures with the same address is a
good tool for troubleshooting unexpected behavior and an easy way to
achieve synchronized action.
Specifying a DMX address
DIP-switch pins 1-9 are used to set the control address:
1 Select an address for the fixture on your controller. If you are calculating
the DMX addresses for multiple fixtures then the Martin Address
Calculator is available on the internet at
http://www.martin.dk/service/utilities/AddrCalc/index.asp
2 Look up the DIP-switch setting using the Martin DIP Switch Calculator
(also available on the internet, at
http://www.martin.dk/service/dipswitchpopup.htm), or look for the address
in the following DIP-switch settings table.
3 Disconnect the fixture from power.
4 Set pins 1 through 9 to the ON (1) or OFF (0) position as listed in the
table.
DMX operation17
Page 18
Find the address in the following table. Read the settings for pins 1 - 5 to
the left and read the settings for pins 6 - 9 above the address. “0” means
OFF and “1” means ON. Pin 10 is always OFF for DMX operation.
For detailed information refer to “Ego X4 specifications’ on page 28.
Channel 1 controls the strobe, stand-alone auto-triggering and reset. If
stand-alone auto-triggering is selected on this channel, intensity will be
18Ego X4 user manual
Page 19
automatically set to 100% and all other channels will be disabled until
stand-alone is deselected on channel 1.
Channel 2 controls the intensity. When the intensity is set to zero, the
cooling fan will slow down significantly to reduce power consumption,
prolong the life of the product, reduce noise and minimize cleaning. This
channel is disabled during stand-alone auto-triggering operation.
Channel 3 controls the gobo/color wheel and is used to select effects and
control rotation of the effect wheel. This channel is disabled during standalone auto-triggering operation.
Music triggering of the color wheel can be selected on this channel in a
range of forms.
Channel 4 controls the effect shake function. This channel is disabled
during stand-alone auto-triggering operation.
Channel 5 controls the parabolic reflector’s rotation direction and speed.
This channel is disabled during stand-alone auto-triggering operation.
Music triggering of the parabolic reflector can be selected on this channel
in a range of forms.
Channel 6 allows one of 12 factory-set macros to be selected. The
macros are mini-programs that use all the fixture’s effects. Select a macro
if you want fast access to impressive light effects with minimal
programming.

CLEANING
Regular cleaning of the elements in the optical path, as well as the fans
and air vents, is vital to maintaining the operational quality of the Ego X4.
Important! Excessive dust, smoke fluid, and particulate buildup degrades
performance and causes overheating and damage to the
fixture that is not covered by the warranty.
Cleaning the fan and air vents
To maintain adequate cooling, dust must be cleaned from the fan and air
vents periodically. Remove dust from the fan and air vents with a soft
brush, cotton swab, vacuum, or compressed air.
Cleaning optical components
Clean the optical components regularly. The presence of smudges or dust
on optical surfaces can reduce the strength of the light output and the
quality of the effects.
Use care when cleaning optical components and work in a clean, well lit
area. The coated surfaces are fragile and easily scratched. Do not use
solvents that can damage plastic or painted surfaces.
1 Disconnect the fixture from power and allow the components to cool
completely.
2 Remove the front lens for cleaning by
grasping the lens collar, twisting it
clockwise, and sliding the lens out of
the fixture.
3 Remove the fixture cover if you need to
access the internal optical
components. You may want to remove
the lamp for cleaning (see the related
steps in “Installing a lamp in the Ego X4’ on page 21).
20Ego X4 user manual
Page 21
4 Vacuum or gently blow away dust and loose particles with compressed
air.
5 Remove stuck particles with an unscented tissue or cotton swab
moistened with glass cleaner or distilled water. Do not rub the surface: lift
the particles off with a soft repeated press.
6 Remove smoke and other residues with cotton swabs or unscented
tissues moistened with isopropyl alcohol. A commercial glass cleaner may
be used, but residues must be removed with distilled water. Clean with a
slow circular motion from center to edge. Dry with a clean, soft and lintfree cloth or compressed air.
7 Replace the lens and fixture cover and tighten the access screws, taking
care not to trap any loose wires.
LAMP MAINTENANCE
Warning!Always disconnect the fixt ure from AC power and allow it to
cool for 5 m inutes be fore inst allin g the l amp.
Import ant!Installing any other lamp may damage t he fixture .
Allow the lamp to cool for at least 5 minutes before packing and moving
the fixture. To avoid possible damage, remove the lamp when shipping
the fixture.
As a general rule of thumb, the halogen lamps that have the shortest life
span provide the greatest intensity.
Installing a lamp in the Ego X4
1 Disconnect the fixture from AC power. If replacing a lamp, allow it to cool
for at least 5 minutes before removing the lamp-access cover. The lamp
cools faster with the cover in place. It can take up to 15 minutes for the
fixture to cool completely.
2 Remove the six access screws from the cover and lift it off.
Basic service21
Page 22
3 If replacing a lamp, grasp the old
lamp by the reflector and pull it out
of the holder. Then pull the socket
off the lamp. Do not pull the wires.
4 Push the socket fully onto the pins
of the new lamp.
5 Clean the glass bulb with the cloth
supplied with the lamp, particularly
if your fingers touched the glass. A
clean, lint-free cloth wetted with
alcohol may also be used.
6 Gently push the lamp into the
holder until it snaps into place.
7 Replace the fixture cover and tighten the access screws, taking care not to
trap any loose wires.
FUSES
The Ego X4 uses a time-delay fuse for protection against current
overload. An indication that the fuse may have blown is that when power
is applied the lamp does not light and the fan does not operate.
If the fuse blows repeatedly, there is a fault with the unit that requires
service by a Martin technician.
Never bypass the fuse or replace it with one of another size or rating.
Replacing the main fuse
1 Unplug the mains cable from the power input socket. The fuse holder is
integrated into the power input socket.
2 Using a flathead screwdriver, lift the cover off the fuse holder and replace
the fuse.
3 Replace the fuse holder cover and reconnect power.
FIRMWARE UPDATES
The factory installed firmware version is indicated on the serial number
label.
The latest firmware is available from the support area of the Martin web
site at http://www.martin.com. It can be installed using an MP-2, or via a
PC serial data link using a hardware interface supported by the Software
22Ego X4 user manual
Page 23
Uploader shareware (also available from the Martin web site). The
following devices are currently supported (in Version 5.5):
• DABS 1 (presently available with the MUM software package)
• LightJockey 4064 ISA DMX Interface Card (DJ and Club versions)
Note: Intermediate control systems such as the Martin Lighting Director
(MLD) and the Martin Matrix must be bypassed when updating fixture
software via the DMX link. These systems do not relay the update code
correctly because it is not a DMX-compliant signal.
Normal update
To update fixture software, connect an upload device to the fixture just like
a DMX controller and perform a DMX mode upload as described in the
uploader’s documentation.
When the upload is completed (and when booting up) the fixture performs
a check-sum test of the memory and then resets.
In the unlikely event that a software upload is interrupted, the fixture must
be powered off for at least 10 seconds to force a check-sum test. You can
then repeat the DMX-mode upload. If an error occurs and the fixtures do
not reset, data was interrupted or corrupted during transmission. Perform
a boot mode upload as described below.
Boot mode upload
If the normal upload procedure does not work, or if the software update
notes call for a boot mode update.
Perform a boot mode upload as described in the manual of the uploader
that you are using.
